Product family
OPTIWAVE 5200 C/F (10 GHz)
for liquids in storage and process applications
OPTIWAVE 5400 C (24 GHz)
for liquids in basic process applications
This 10 GHz 2-wire FMCW radar level transmitter 
measures distance, level, volume, mass and flow 
rate of liquids and pastes. It is ideal for corrosive 
products with its PP or PTFE antenna options. It 
features unique PP and PTFE antennas for 
aggressive products. The device is able to measure 
distances up 30 m / 98.4 ft in process conditions up 
to +250°C / +482°F and 40 barg / 580 psig.
The device agrees with SIL2 requirements for 
safety-related systems (as per IEC 61508). Output 
options include HART®, FOUNDATION™ fieldbus 
and PROFIBUS PA industrial communication 
protocols.
Designed for basic liquid applications, this market 
entry 24 GHz 2-wire FMCW radar transmitter 
provides accurate readings even in fast moving 
processes, in closed tanks or in the open air like 
rivers or dams. Its proven PP Drop antenna is 
insensitive to condensation.
The OPTIWAVE 5400 can measure in process 
conditions with temperatures up to +130°C / +266°F 
and pressures up to 16 barg / 232 psig. The antenna 
options permit to measure distances up to 100 m / 
328 ft. The device can be installed in high nozzles 
(≤1 m / 3.28 ft) when it is fitted with antenna 
extensions.
